When i found the http://arduino.cc/en/Tutorial/ArduinoISP tutorial i wanted to make my own stand alone arduino.I bought a couple of atmega8s and put the bootloader on them with my arduino mega2560.That worked fine and i can see the bootloader working on my diy arduino.(three flashes of the led).But i cant get it to upload a sketch to it. When i try to upload it's saying: avrdude: stk500_getsync(): not in sync: resp=0x00Does anyone know how to get it working propperly?

The complete diy arduino is based on : http://arduino.cc/en/Main/Standalone

I used my arduino mega2560 to bootload the atmega8.I made some pictures but i don't know how to upload them here.for uploading my sketches I use: CP2102 USB to TTL Converter Module which i bought from here: http://dx.com/p/cp2102-usb-to-ttl-converter-module-red-146141

Okay... so you used the Arduino as ISP? Which board did you select (i.e. which bootloader did you put on the ATmega8?)?

Cool, at least this CP2102 has the DTR/RST broke out. Did you install the driver?http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

Did you put a 0.1uF capacitor between RST on the USB2UART and pin 1 on the Atmega8? This allows the auto-reset, other than that, you will have to use the reset button just before the upload (when the sketch size appears).

is it possible I somehow burned out my atmega?

It is always possible But I do not think we can make that determination, unless you have already release the "blue smoke" from the chip.

i tried it a couple of times like that but it's not working.the USB2UART i'm using is slitchly different than the one in the link.it is the one i ordered but apperently it has changed.mine doesn't have a TX led.

Well that is unfortunate. Lets try a manual reset. When you press the upload button and the IDE compiles the sketch, press and hold the reset button down until the Binary Sketch Size: 1,234 bytes appears in the IDE window and then release the reset button. There is a fussy timing of this, so a few tests may be needed (delaying release 100-500ms after the Binary Sketch Size). Some people prefer just pressing it when the Binary Sketch Size appears.
